The construction of the cnrria fe and platen and mechero ism for shifting the littter may be of any appropriate ('lraraoter.

As shown, the carriage travels upon rails 2.9 and 30, mounted in brackets located at the sides of the frame. The platen 31 is mounted in s frame 32, carried in the ends of par'allel pivoted arms 35.. 34, extendinghorizontally from tlc carriage. The lower arms 34 are festin the ends of a rock-shaft 35, from the center of which projects an erin 36, whose end is acted upon by a cross-rod 37, held in the ends of bell-crank levers 38, located at the sides of the machine and fast, to a rocksliaft 39. The bell-crank 38 at the left-hand side of the machine has connected to it a link 4() to be suitably actuated on the depression of' a shift-key. f l

The relation of the type-bars and Henin connections is much the saine, affording sulqstantial uniformity of behavior. The-structure is light, cheap, and simple and affords a marked refinement of touch of the fingerpieces.

The oint of connection between links 7 and i3 is in front of the hinge-joint connecting the links 6 7 and, as shown in this instance, is about midway between suoli hinge-bint and the pivotal connection of link 7 wit its iis-ed or anchor ieee 4. In this construction the link 6 is sulijected to tensile strain onl and may therefore be a light wire or cor The link 7. while subjected to similar tensile strain, is 'also subjected to lateral strain and is shown as made of stiff flat metal. An or-A ganization of this kind allords a ood toucli and high acceleration of the typesr. Pref? erably the joints between the members of the' flexing connection and between it and the fixed point and type-bar are such as to allow sli lit twisting movements. This is particular f desirable at the type-bars near the ends of t e segment. Such joints havin this capacit f may for convenience be cal ed universa joints.

The arrangementdesignated by me a flexing connection" may have in Sonie forms the full operation of a reverse or accelerating toggle and-iii all forms is of the nature of suoli n' toggle. As illustrated, application of power thereto is in a line intersecting one drawn between the f'nied point and the point of attiichnient to the type-bar.
